(c)When a prescribed level of malapportionment is achieved and sustained in the state or territory;
(d)When there is a change in the number of members of the House of Representatives to be chosen in the state or territory at a general election, as determined approximately one year after each general election;
(k)When seven years have elapsed since the state or territory was last redistributed. Of the three possible "triggers" for redistributions, change in representation entitlements has been by far the most important and has accounted for the majority of redistributions initiated since 1984.
There have been no redistributions triggered by malapportionment.
The rules governing the timing of redistributions are based on objective criteria, and do not permit the government of the day any discretion with regard to the scheduling of redistributions. The rules also clearly ensure that there is a limit on the length of time that can elapse between redistributions, which has tended to limit the extent to which malapportionment can arise.

k. Boundaries redrawn every____period of years

Federal electoral boundaries are adjusted after each decennial census to reflect changes in population, this process is called redistrubution.In Newfoundland and Labrador, Nova Scotia, Manitoba, Saskatchewan and Nunavut redistribution also takes place every 10 years. In Prince Edward Island, electoral boundaries are reviewed after every third general election. In Quebec, Alberta, British Columbia, Yukon and the Northwest Territories, they are reviewed after every second general election. In New Brunswick, redistribution proceeds only after an Order in Council. In Ontario, according to the Representation Act, 1996, the electoral districts are identical to those established for federal elections, and there is no provincial redistribution. Under the Representation Act, 2005, this process of redistribution will not apply to Ontario’s northern ridings after September 2007.

In India boundaries are meant to be examined after the ten-yearly census to reflect changes in population, for which Parliament by law establishes an independent Delimitation Commission, made up of the Chief Election Commissioner and two judges or ex-judges from the Supreme Court or High Court. However, under a constitutional amendment of 1976, delimitation was suspended until after the census of 2001, ostensibly so that states’ family-planning programmes would not affect their political representation in the Lok Sabha and Vidhan Sabhas. This has led to wide discrepancies in the size of constituencies, with the largest having over 25,00,000 electors, and the smallest less than 50,000.

Before each election, the local authorities decide whether to keep the existing boundaries or change them due to, for example, new settlements. For boundaries to be changed there has to be essential changes in the population structure.

There are no specific provisions in the electoral legislation or the Constitution except the ability to subdivide Districts into wards and the ability by Parliament to make "special provisions" for parts of Tuvalu with special "electoral problems". To redraw boundaries would mean an amendment of the Electoral Provisons Schedule 1. There is a discrepency in both the Constitution and Electoral Provisions in that they both state what should constitute a District(Constituency) but make no provision to change the composition of that District should that District no longer comply with definitions in the Constitution or Electoral Provisions.
